The present invention relates to a container for the microwave heating of a food product in which a sheet of barrier material is sealed around a food product to a blank having one or more panels which can be folded to assemble a container. The sheet of barrier material forms a pocket inside which a food product may be disposed. The sheet of barrier material is sealed to one of the panels, so that a peripheral outer portion is formed to separate the food product from the remaining panel or panels. The barrier material may be moisture impervious, and may be sealed to the blank using a vacuum platen or heat-sealing methods. A microwave susceptor can be disposed on the blank, which is made from a material suitable for microwave heating such as a polymer and paperboard laminate.

What is claimed is: 1. A container for microwave heating of a food product, comprising: a blank having an upper face and a lower face and two or more panels, wherein at least one of the panels is capable of being folded relative to the other panels; and a sheet of barrier material forming a pocket
What is claimed is: 1. A container for microwave heating of a food product, comprising: a blank having an upper face and a lower face and two or more panels, wherein at least one of the panels is capable of being folded relative to the other panels; and a sheet of barrier material forming a pocket for containing a food product, the sheet of barrier material having an interior surface and an exterior surface, the interior surface of the barrier material being sealed to the upper face of the blank on one of the panels around the pocket so that a peripheral outer portion is formed to separate the food product from the at least one of the panels. 2. The container of claim 1, further comprising a microwave susceptor. 3. The container of claim 2, wherein the microwave susceptor is selected from the group consisting of a metallized film, a metal-based dispersion, a conductive coating and any suitable combination of the foregoing. 4. The container of claim 2, wherein the microwave susceptor is applied to either the lower face or upper face of the blank. 5. The container of claim 2, wherein the microwave susceptor substantially covers the blank underneath the pocket. 6. The container of claim 1, wherein the blank is moisture-impervious. 7. The container of claim 1, wherein the blank comprises a polymer and paperboard laminate. 8. The container of claim 1, wherein the sheet of barrier material is moisture-impervious. 9. The container of claim 1, wherein the sheet of barrier material comprises a polyester film. 10. The container of claim 1, wherein the pocket is formed in the sheet of moisture-impervious barrier material using a vacuum platen. 11. The container of claim 1, wherein the sheet of barrier material is continuously sealed to the upper face of the blank around the pocket by heat sealing. 12. The container of claim 1, wherein the blank further comprises a generally rectangular floor panel and four wall panels, the wall panels being folded upwardly to form approximate right angles with the floor panel. 13. The container of claim 1, further comprising a food product. 14. The container of claim 1, wherein said blank further comprises a moisture barrier. 15. A container for microwave heating of a food product, comprising: a blank having an upper face and a lower face, the blank comprising a floor panel and one or more edge panels, the edge panels capable of being folded upwardly relative to the floor panel; and a sheet of barrier material forming a pocket for containing the food product, the sheet of barrier material having an interior surface and an exterior surface, the interior surface of the barrier material being sealed to the upper face of the floor panel around the pocket so that a peripheral outer portion is formed to separate the product from the at least one edge panel. 16. The container of claim 15, further comprising a microwave susceptor. 17. The container of claim 16, wherein the microwave susceptor is selected from the group consisting of a metallized film, a metal-based dispersion, a conductive coating and any suitable combination of the foregoing. 18. The container of claim 16, wherein the microwave susceptor is applied to the upper face or lower face of the blank. 19. The container of claim 16, wherein the microwave susceptor substantially covers the blank underneath the pocket. 20. The container of claim 15, wherein the blank is moisture-impervious. 21. The container of claim 15, wherein the blank comprises a polymer and paperboard laminate. 22. The container of claim 15, wherein the sheet of barrier material is moisture-impervious. 23. The container of claim 15, wherein the sheet of barrier material comprises a polyester film. 24. The container of claim 15, wherein the pocket is formed in the sheet of moisture-impervious barrier material using a vacuum platen. 25. The container of claim 15, wherein the sheet of barrier material is continuously sealed to the upper face of the floor panel around the pocket by heat sealing. 26. The container of claim 15, wherein the blank further comprises a generally rectangular floor panel and four wall panels, the wall panels being folded upwardly to form approximate right angles with the floor panel. 27. The container of claim 15, further comprising a food product. 28. The container of claim 15, wherein said blank further comprises a moisture barrier. 29. A container for microwave heating of food, comprising: a blank having an upper face and a lower face, the blank comprising a floor panel and one or more edge panels, the edge panels capable of being folded upwardly relative to the floor panel; a sheet of barrier material forming a pocket for containing a food product, the sheet of barrier material having an interior surface and an exterior surface, the interior surface of the barrier material being sealed to the upper face of the floor panel around the pocket so that a peripheral outer portion is formed to separate the product from the at least one edge panel; and the food product located in the pocket.
